vue实现elementui的table和datepicker的操作

yxh168

组件对象说明

      一个组件分别有自己的 属性 Attributes    事件Events    方法Methods

      调用属性和调用事件的形式是不一样的  属性是用  :props     事件是用 @event   所以在使用之前一定要弄清楚给组件添加的是属性还是添加事件

    <!-- 表格组件 -->
    <el-table :data="data"
              :height="height"
              :span-method="spanMethod"
              ref="table"
              @selection-change="handleSelectionChange"
              @sort-change="handleSortChange"
              v-loading="loading">

:span-method 表示接收属性
spanMethod是从子表格组件中传递过来的属性名称
@selection-change 表示接收事件

<script>
  export default {
    data() {
      return {
        // 表格高度
        tableHeight: 0

具体效果

 

注意es6对属性类型的强制性检查 如果声明属性的类型和返回的类型不匹配 会造成一些异常

    props: {
      // 表格数据
      data: {
        type: Array,
        default() {
          return [];
        }
      },
      // 表格列配置
      columnConfig: {
        type: Array,
        default() {
          return [];
        }
      },
      // 表格高度
      height: {
        type: [String, Number],
        default() {
          return 400;
        }
      },
      //表格是否显示折叠信息
      expand: {
        type: Boolean,
        default() {
          return false;
        }
      },
      // 分页参数-当前页
      pageIndex: {
        type: Number,
        default() {
          return 1;
        }
      },
      // 分页参数-每页条数
      pageSize: {
        type: Number,
        default() {
          return 10;
        }
      },
      // 分页参数-每页条数候选项
      pageSizes: {
        type: Array,
        default() {
          return [10, 20, 50, 100];
        }
      },
      // 分页参数-总条数
      total: {
        type: Number,
        default() {
          return 0;
        }
      },
      // 是否显示loading
      loading: {
        type: Boolean,
        default() {
          return false;
        }
      },
      spanMethod: {
        type: [Function],
        default() {
          //函数类型的属性就一定要返回一个函数
          return ()=>{};
        }
      }
    }

elementUI实现表格和合并

    实现效果

         按照业务类型和应用名称进行去重合并单元格

         这个功能对后台返回的数据列表格式是有要求的 必须按照需要被分组的列进行排序(可以是升序也可以是降序) 

         属于同一个业务类型或者应用名称的记录必须排列在一起

 

   如果返回的数据不是有序的  那么页面的显示会如下

 

 

 后台返回的数据列表businessname的值是由暂无业务代码和业务代码1随机排列的 导致页面表格按照业务代码合并行列时出现异常

 

 

 

解决办法 在后台查询好数据后按照业务代码先进行排序 然后再返回给前端

        userChoiceTime_start = self.formartStartTime(startTime)
        userChoiceTime_end = self.formartEndTime(endTime)
        index_list_pattern=self.getindexes(startTime,endTime)
        pageIndex = int(pageIndex)
        pageSize = int(pageSize)
        if sortColumn=="":
            sortColumn = "businessname"



        reverse=False
        floatflag=False
        if sortType == "desc":
            reverse=True
        if sortColumn in ["avgtime","requestCount","errRequest","maxtime","mintime"]:
            floatflag=True
        if floatflag:
            ilist = sorted(ilist,key=lambda e:float(e.__getitem__(sortColumn)),reverse=reverse)
        else:
            ilist = sorted(ilist, key=lambda e:e.__getitem__(sortColumn), reverse=reverse)



        if querytype != "excel":
            reslist=ilist[(pageIndex-1)*pageSize:pageIndex*pageSize]
            data = {\'code\': \'SUCCESS\', \'message\': \'\', \'data\': {"total":len(ilist),"list":reslist}}
            return data
        else:
            data = {\'code\': \'SUCCESS\', \'message\': \'\', \'data\': {"total": len(ilist), "list": ilist}}
            return data
